A tourist walks past the Jiayu Pass, the starting point of a section of the Great Wall constructed during the Ming Dynasty (1368-1644), in Jiayuguan City, northwest China's Gansu Province, April 16, 2013. China will pour 2.03 billion yuan (about 328 million US dollars) in maintaining the Jiayu Pass, also including the construction of a world culture heritage inspection center and a heritage protection and display project. Built in 1372, the Jiayu Pass also served as a vital passage on the ancient Silk Road. It was listed on UNESCO's World Heritage List in 1987. [Xinhua/Lian Zhenxiang]
